Ok, I'd have to say that, as far as CRAZY Chopins go, it doesn't get any crazier than Etude 10/4 (I have actually destroyed a key playing the coda, not to mention two different strings...), Scherzo 1, and the coda (and prestissimo) section of Ballade #2, and not only that, I'd have to agree with Tempest Sonata (who started this post), I'm crazy about crazy Chopin. Although, I'f you like tempestuous music, go no further then the third of Beethoven's Appasionata (is that what some have been refering to as the Tempest Sonata?? Beethoven suggested reading "The Tempest" by Shakespear to better interpret the work...). Even Chopin rarely get's any crazier than that.
